It is termed benign because it rarely progresses to clinically significant renal insufficiency or renal failure. ==Morphology== The kidneys appear symmetrically atrophic and there is a reduced nephron mass.〔 The kidneys have a surface of diffuse, fine granularity that resembles grain leather. Microscopically, the basic anatomic change consists of hyaline thickening of the walls of the small arteries and arterioles (hyaline arteriolosclerosis). Under a microscope, this appears as a homogeneous, pink hyaline thickening at the expense of the vessel lumina, with loss of underlying cellular detail. The narrowing of the lumen restricts blood flow, resulting in ischemia. All structures of the kidney can show ischemic atrophy although glomerular ischemic atrophy may be patchy.〔 In advanced cases of benign nephrosclerosis the glomerular tufts may become globally sclerosed. Diffuse tubular atrophy and interstitial fibrosis are present. Often there is a scant interstitial lymphocytic infiltrate. The larger blood vessels (interlobar and arcuate arteries) show reduplication of internal elastic lamina along with fibrous thickening of the media (fibroelastic hyperplasia) and the subintima.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Benign nephrosclerosis」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
